| 摘 要： | 建立液-液萃取气相色谱法电子捕获检测器(GC/ECD)同时测定饮用水中12种挥发性消毒副产物(Disinfection byproducts, DBPs)的方法.采用过程标准校正降低预处理过程中引入的误差,方法检出限为0.08~0.21 μg/L, 全部组分在21.50 min内测定完成.不同浓度的DBPs在自来水和地表水中的回收率为80.9%~115.7%,相对标准偏差在0.9%~9.9%之间.各组分在0.5~200 μg/L浓度范围内线性关系良好,相关系数R>0.99.应用本方法测定了饮用水和地表水及其氯化后样品中DBPs的含量.本方法简便、快速、稳定,满足饮用水中挥发性DBPs的检测要求.

| Abstract: | A method for simultaneous determination of 12 kinds of chlorinated disinfection byproducts (DBPs) in drinking water was developed based on liquid-liquid extraction gas chromatography equipped with electron capture detector (GC/ECD).The procedural standard calibration was adopted to eliminate the interference of different matrix.The method detection limits for 12 DBPs were 0.08-0.21 μg/L and the entire analytical procedure was finished in 21.50 min.The recoveries were in the range of 80.9%-115.7% and the relative standard deviations (RSD) were between 0.9% and 9.9% at different concentration levels (5 and 50 μg/L) in tap water and surface water.The correlation coefficients for all 12 kinds of DBPs were greater than 0.99 in the linearity range of 0.5-200 μg/L.The method was applied to determine DBPs in drinking water and source water.This method was rapid and competent for detection of volatile DBPs in drinking water. |
